Exploratorium Science at America's Cup:  Green Sea Turtles (Clip)
Running Time:
04:55
There are green sea turtles in San Diego Bay? Where did they come from? Do they really live over 100 years? Why is it important for scientists to keep track of these giant creatures, and how on earth do they do it? In this interview with ecologist Tomoharu Eguchi (NOAA Marine Fisheries Service) and ecology graduate student Sheila Madrak, we meet the sea turtles and explore these 'big' questions.

Exploratorium Science at America's Cup:  Wind Modeling (Clip)
Running Time:
02:50
The Southern California Coastal Ocean Observing System (http://sccoos.org/) gathers live data about winds, waves, surface currents, temperature, and water quality, and makes it available to everyone. In this piece, Oceanographer Art Miller tells us about this system, and about how America's Cup sailors can use this kind of data and modeling to improve their race performances.

Science in the City:  Rebuilding Doyle Drive (Clip)
Running Time:
00:03:50
At the southern end of the Golden Gate Bridge, a construction project to rebuild the elevated freeway ramp formerly known as Doyle Drive is underway. Senior bridge engineer John Walters tours us through some of the new seismic technologies being installed, including a seismic joint designed to handle several feet of longitudinal movement and a spherical bearing that allows for three-dimensional movement. Walters also points out a temporary structure built over the historic Presidio Pet Cemetery to protect the grave sites while providing a platform for the construction overhead.

Exploratorium at the Piers:  Jitterbugging: Pouring Concrete at the Piers (Clip)
Running Time:
00:01:51
Pouring concrete is an ongoing feature of construction at the Piers. This footage, captured in July 2011, shows the well-choreographed process involved, from pumping the concrete into rebar-latticed slabs via remote-controlled overhead boom, to vibrating the concrete to get rid of air pockets, to flattening the surface using 2x4s (“screed”) and rakes (“come-along tools”), to tamping in (“jitterbugging”) bits of sand and gravel, to the final smoothing and leveling of the finished surface. This pour created an extension to the southeast apron of Pier 15, adjacent to what will become the East Gallery.
